Eco-carpark by the beach at Seven Mile

DirtGlue® eco-carpark

From a distance, it looks like any normal red gravel car park. However, get up close, and you’ll discover that the gravel surface is solid, rock solid.

Project: Red gravel and DirtGlue® car park in Seven Mile Beach, Tasmania
Date: September 2016
Client: Clarence City Council

Background

There are numerous red gravel car parks along the coastal road at Seven Mile Beach, 15 minutes east of Hobart. Red gravel is an effective short term solution to surfacing these car parks – the gravel is easily available and relatively low cost. However, it has its shortcomings; the gravel quickly becomes displaced due to cars driving on it and bad weather. Typically the surface develops pot holes and when this occurs, the Council sends in a crew to reset the levels and lay more red gravel. Another major issue is the loose gravel from the car park gets washed into the drains and underground pipes. Over time, this causes significant problems for the drainage system.

Clarence Council approached us to see if DirtGlue® could provide a better long term solution for this car park’s maintenance strategy.

The Council wanted to steer away from concrete, bitumen and asphalt, as this was cost prohibitive and also not appropriate for the site.

For this scenario, using DirtGlue® Industrial was a great fit for the project – a long lasting sealed gravel surface, cost effective, environmentally safe and a natural finish that fitted in with the local environment.

Outcome

After the Council had prepared the base and laid the gravel it took just half a day for our GreenTrack contractor (D Howard Landscapes and Excavations) to apply the DirtGlue and roll the surface. The car park was closed to the public for just four days.

GreenTrack and DirtGlue® delivered exactly what was expected. This 230 square metre car park at Seven Mile Beach now has a sealed red gravel surface; it is rock hard and wearing well. From a distance it looks no different to the original red gravel car park, local residents may not have even noticed the change.

Inspecting the drains around the site, it can be seen that the drains being fed by water running off the car park are relatively gravel free. Whereas, other nearby drains are clogged with gravel washed in from red gravel paths along the road side.

Stabilising walking tracks in the Ku-ring-gai Wildflower Garden

Stabilising walking tracks in the Wildflower Garden

Ku-ring-gai Wildflower Garden is one of Sydney’s best kept secrets. Situated in St Ives, the 123 hectares of urban bushland is a great spot for bush walking and outdoor adventure.

There is a network of tracks through this extremely environmentally sensitive area. The local council has major issues with track erosion, especially when it rains. The soil is very sandy and walking tracks regularly wash out during heavy downpours. This leads to the paths being closed to visitors for safety reasons. The council needed to stop the erosion and DirtGlue was the best solution.

Tracks were treated with a surface application of DirtGlue Industrial. Quite simply, spraying a mixture of DirtGlue and water onto the dirt. Well known problem areas were treated as a priority, stabilising paths, steps and rock structures. The contrast between treated and untreated areas is significant.

Furthermore, because of a preference to avoid cement/concrete in this environmentally sensitive area, parks staff have installed signage posts into the ground using Dirtglue instead of concrete.

On a quiet walking track on Hobart’s Eastern Shore, Greentrack collaborated with Clarence Council on the installation of a memorial seat. Usually, this style of seat is bolted into a concrete slab, however for this installation the goal was to avoid using concrete.

This seat was bolted into a slab of limestone gravel and DirtGlue Industrial. Limestone gravel was chosen to blend with the gravel in the walking track alongside.

The project was a great success. The bench sits very naturally in the bush setting and no concrete was used.

Walking track connects West Hobart Oval to the community

In April 2017, Greentrack installed a gravel and DirtGlue walking track for the City of Hobart, as part of a major development of the West Hobart Oval.

Background

During the Council’s project planning, the feedback from the community consultation requested a sealed track that didn’t suffer potholes. However, the community also didn’t want concrete or bitumen.
Gravel and DirtGlue was a great solution.

The paving for the track was constructed with DirtGlue Industrial and a blend of locally sourced gravels, Tasmanian Gold and Blue Metal. Steel was used to edge the pathway.

Outcome

The outcome was a long lasting, sealed gravel track, radiating the soft natural colour of Tasmanian Gold. Furthermore, like all Greentrack’s products, the bonding agent, DirtGlue Industrial, has zero toxicity and is friendly to the environment.

Thoughts on Safer Mining Environments

safer mining environments with Global Environmental Solutions

Mining is one of the oldest industries in the world. And, it will remain one of the backbones of our economy and that of many other nations long beyond our lifetimes. That said, one of the recurring trends in the U.S. media is the often adverse working conditions for employees as well as the ever-present concern about damaging the environment.

Here’s the good news:

Good environmental practices and mine safety are easily attainable and is far more affordable than you might think. And, while you may have needed several different contractors to meet regulations before, Global Environmental Solutions (GES) is your one-stop-shop to meet and exceed environmental and site-safety specifications.

Areas you can utilize our products:

  • Above ground and under ground haul roads
  • Capping above ground tailings/stockpiles
  • Tailing dams
  • Pond lining
  • Stabilizing backfills
  • Re-vegetation
  • Crushers
  • Conveyors
  • And many more!

The activity of mining means the creation and existence of dust. It affects everything from the surrounding ecosystem, to the lungs of miners, to the health of equipment, and surrounding communities due to environmental shifts (wind), etc. That said, all mining sites are unique, so you need a partner that can provide a solution that takes care of all-of-the-above customized to your site’s needs.

GES dust suppression products we’ll use to shape your solution:

DustLess®

  • Dust control for any dirt driving surface (continuous traffic, high traffic, heavy traffic)
  • Underground mining operations
  • Non-aqueous tailing pond dust control (for below freezing temps)

DirtGlue®

  • Erosion control
  • Stockpile capping
  • Sediment control
  • Stockpile sealing
  • SWPP management plans
  • Embankment stabilization
  • Contaminated soil containment
  • Eliminate TSS in storm water run-off
  • Dust control on non-driving surfaces
  • Replace conventional tackifier in Hydro-seeding applications
  • Tailings ponds

CompoMulch™

  • Re-vegetation for permanent erosion control and dust control

Our products can be used to develop dust management, sediment control and stabilization for your unique requirements. Our DustLess product is absorbed by the dust particles, which stabilizes them and keeps them from entering the air and getting swept about. DirtGlue, which is an acrylic polymer, is applied to non-traffic areas such as soft shoulders and adjacent stockpiles and embankments. The polymer forms a tough protective crust that stops the dust created by the vacuum effect of passing vehicles. When applied to stockpile and embankments, DirtGlue also protects against sediment runoff as well as wind and water erosion issues. If revegetation is needed DirtGlue polymer can be used as a tackifier in conjunction with CompoMulch to vegetate nearly any surface of nearly any soil type.

Coal Bunker Sealing

DirtGlue polymer stockpile capping and sealing is the antidote to the oxidation and moisture that leads to spontaneous combustion in coalbunkers. Keeping coalbunkers sealed mandates an effective, reliable air-blocking system. Sealing coalbunkers is, of course, more necessity than choice. Air circulating through the coalbunkers is a precursor to spontaneous combustion, a serious danger to a power plant, its employees, and the value of the stored coal itself. The spraying of DirtGlue polymer on stockpiles or bunkers causes the formation of a thin crust much like a spray-on tarp to act as a seal against water and air. This protective seal helps prevent fire, dust, erosion and loss of BTU’s.

Benefits:

  • Eliminate air and water penetration
  • Control dust through encapsulation
  • Minimize oxidation to prevent spontaneous combustion
  • Prevent costly coal bunker fires
  • Slow coal deterioration and water absorption that can reduce BTU value
  • Get the desired results without the higher cost of nitrogen injections

Further, when it comes to the transport of mined coal we can help with transportation efforts of the resource, as statistics show that a typical 3-5% loss of coal is experienced during transport from the mine. This can be avoided by “capping” the train or truck hopper hauling the load with one of our environmentally friendly spray-on solutions.
